Create Log Field
I would like to know how can I create log field.
I want to track the changes made to a customer's record and to be reflected in another field (log field), for example to have comments like these:
01/01/2010: record created
01/02/2010: field "whatever" changed to "whatever"
01/03/2010: field "whatever" changed to "whatever"
and so on
or something like that.
Thanking you in advance.
